Background The pathogenesis of systemic sclerosis (SSc) is thought to result from interactions between epigenetic features and environmental factors, leading to the onset and progression of the disease in genetically susceptible patients (1). Case reports of women with silicone breast implants who developed SSc have been published, but case-control and prospective studies in connective tissue diseases often failed to find an increased risk of SSc associated with silicone cosmetic surgery (2,3). These studies have several limitations, including heterogeneous cohorts of enrolled patients not selective for SSc, non-homogeneous disease duration or disease stage at study entry. For these reasons, the possible effect of silicone implants as immune adjuvants is highly suspected but remains unclear (4). Objectives Retrospective study of SSc patients, to find out who developed SSc after silicone cosmetic surgery. Methods The clinical files of 140 female patients with systemic sclerosis were retrospectively evaluated and clinical data collected. Results Five patients showing a history of silicone cosmetic surgery (3.6%) before SSc development were identified. The brief clinical histories of the five patients are below reported, showing very similar outcomes after silicone implant. 1. TC 47-year-old female underwent cosmetic breast prosthesis: twelve months later she experienced Raynaud’s phenomenon (RP) and diffuse cutaneous SSc after 10 further months; antinuclear antibodies were positive with a speckled and nucleolar pattern, but specific SSc-related autoantibodies negative. 2. LS 28-year-old female underwent cosmetic breast prosthesis: twenty-two months later RP appeared and anticentromere antibodies (ACA) positive aggressive diffuse SSc was diagnosed one year later. 3. PJ 38-year-old female underwent cosmetic breast prosthesis: eleven months later she experienced RP and after 10 further months, aggressive diffuse cutaneous SSc; antinuclear antibodies were positive with a speckled patter, but specific SSc-related autoantibodies were negative. 4. CM 58-year-old female who underwent cosmetic lip silicone application: one year later she complained of simultaneous onset of RP and very aggressive diffuse cutaneous SSc with anti-topoisomerase positivity; she died during follow-up. 5. BS 33-year-old female who underwent cosmetic breast prosthesis: twenty months later she complained of RP and after ten further months, limited cutaneous SSc with ACA positivity; SSc clinical condition partially improved and its progression stopped after prosthesis removal. Globally, after silicone implant, RP occurred in a mean time of 15±5 months and SSc in 23±8 months. Conclusion This study reports a prevalence of 3.6% of silicone cosmetic surgery before SSc onset, interestingly with a close and similar temporal association between silicone implant and disease development. This finding suggests a possible role of silicone in SSc pathogenesis (ASIA syndrome). Specifically addressed large clinical studies or big-data studies need to rule out this matter.
